6.3.1 The Beck Self-Concept Inventory for Youth: descriptive statistics<br />

The graphs in figure 6.3.1 show the difference in the scores for each group’s answers<br />

of the BSCI between the first and second wave of data collection.<br />

There was, approximately, a 50:50 split of students in group A showing an<br />

increase:decrease in their self-concept scores whereas in group B 75% reported an<br />

increase and only 25% a decrease. This could look as though students who have had<br />

music therapy scored less well than students who had not. However, it could further<br />

support to the suggestion made previously (6.2.1) that music therapy helps develop a<br />

stronger sense of self and group A, therefore, give more honest and insightful answers<br />

than B.<br />

The summary statistics (table 6.3a.i in appendix 6.3a) show that the students in both<br />

groups have a similar maximum score (group A=11, group B=12) and, although the<br />

mean declines in group A (mean= -2.85), the standard deviation was wider than group<br />

B (SD = 9.06), which reflects the increased uncertainty in their responses. Group B<br />

answered more consistently (mean = 5.00, SD = 6.95) and came across as more selfassured.<br />
